POLYMERIC DIORGANOTIN CATALYSTS OF USE IN POLYURETHANE SYSTEMS |
摘要 |
Useful as catalysts for the reaction of a polyisocyanate or a partially blocked polyisocyanate with a hydroxy-containing compound are organotin compositions obtained by reacting a diorganotin oxide of the formula R2SnO or a diorganotin dichloride of the formula R2SnC12 with a compound of the formula HS-CH2CH(OH)CH2XH where R is a C1-C8 alkyl or an aryl group and X is -O- or -S-. Also disclosed are cationic electrodepositable (CED) compositions containing such catalysts.
